Python

The Python programming language is an interpreted, duck-typed language.

On most platforms, the interpreter is called by python(1). Some platforms distribute with version suffixes that may or may not be optional. The py(1) launcher is also available.


Example

print("Hello, world")

A program is more commonly structured like:

def main():
    print("Hello, world")

if __name__ == "__main__":
    main()

If using Python 2, the print command is instead a statement.

print "Hello, world"

To run the program, try:

python hello.py
